CAR-DOOFL SPECIFICATION forming part of Letters Patent No. 325,218,dated August 25, 1885.

Application filed June 29, 1885.

To all whom it may concern Be it known that I, DAVID SUTHERLAND, i

of the city of St. Louis, State of Missouri, have invented certain newand useful Improvements in Car-Doors, of which the following is a full,clear, and exact description, reference bein g had to the accompanyingdrawings, form ing part of this specification, and in which- Figure 1 isa front elevation of my improved doors. Fig. 2 is a transversehorizontal section taken on line 2 2. Fig. 3 is a detail hori zontalsection taken on line 3 3, Fig. 1; and Fig. 4 is a detail verticalsection taken on line 4 l, Fig. 1. Fig. 5 is a modification.

My invention relates to doors intended more particularly forrefrigeratin gears; and my invention consists in features of noveltyhereinafter fully explained, and pointed out in the claims.

Referring to the drawings, A represents the door-jamb, or part of arefrigeratingcar, and I3 the doors hinged thereto at 0. Above the doorsis secured a strip, 1), being separated by means of brackets D,depending from the door-jainb, and screw-bolts I, projecting outwardfrom the strip and passing through the tal section, in which thepacking-strip IV is drawn in by means of a screw, I, which passes lowerends of the brackets, outside of which they are provided with nuts J.The strip is wedge shape in transverse section, as shown in Fig. 4,being wider at its inner than at its to fit a key or wrench, and may, ifpreferred,

outer part. 011 both its lower and upper face is secured a packing, L,the upper one forming a tight joint between the strip and the door-jamb,and the lower one forming a tight the latter are closed. In case thesejoints become loose by wear, a strip is moved slightly outward bytightening on the nuts J, and thus perfectly tight joints are bad at alltimes at the tops of the doors, and a per- 1 substantially as and forthe purpose set forth.

fectly-tight joint is made between the doors by means of a similarstrip, N, connected to one of the doors by means of spring or other arms0 and bolts T. This strip N is also wedge shape in transverse section,and either i it or the adjacent edges of the doors are pro vided withpackings T. (See Fig. 3.) The inner bolts, T, pass through slots in theends of the spring-arms to allow for horizontal movement of the strip topermit it to be forced inward more or less to insure a tightjoint be-(N'o model.)

tween the doors. It is forced inward by hand nuts U on the outer end ofscrew-threaded rods V, that project from the doors, to which the armsare secured through slots IV in the arms.

In Fig. 2 the strip is shown forced in bythe handnuts, forming a tightjoint between the doors, and in Fi 3 it is shown held out by means ofthe springarms, the nuts being turned outward to permit the arms toassume this position.

The doors may be held closed by any desirable means. I have shownvertical sliding bars or catches X, that engage their outer ends withbrackets or staples Y, secured to the doorjamb and connected at theirinner ends to a central link, Z, pivoted to one of the doors andprovided with a lever, Z, by which they are operated, and which has aslot, Z to engage a lug, Z, and one of the arms to hold the catches intheir outer position into engagement with the said brackets. Todisengage the catches from the brackets the parts are moved intoposition shown by dotted lines.

In Fig.5 is shown a modification in horizonthrough the strip and screwsin a bracket or lug, D, that is secured to the inner side of the door B.The head I- of this belt is made 2. In combination with the doors, thewed geshape adjustable strip provided with packingstrips and locatedabove the doors, substantially as and for the purpose set forth.
